Fob,

I totally understand your situation man. Been there, done that. (not saying I went to restroom when cheque came. hehe).

Here's what you need to do.

GET AWAY FROM THESE PEOPLE. Why on earth are you living with a COUPLE? LOL.

For the couple, the world revolves around them and you are just a pawn. The guy may be cool, the girl may be cool, but the couple, the couple is on a mission to survive anything and everything anyhow!

After you've gotten away from them, choose your circle carefully. I'm not saying avoid all Nepalis like its the plague, but there are some who you should not mingle with. These are the ones who will try and put "nepali peer pressure" on you, make fun of "khaires" and their habits, generally be unproductive in college and dont even have ONE non-nepali friend. AVOID AT ALL COSTS OR YOU RUIN YOUR COLLEGE EXPERIENCE.

It's college dude. Go out and experiment, find something you would be interested in doing for the rest of your life. It might even be your shot at happiness. if you went to college in nepal, it would be very hard for you to love something mainly because if that something you love does not go well with your friends, they will tease and ridicule you until you drop it. FCK THAT SHT :)

Our samajhik perspective was right in the situation it was created in, which is back home. Here, it fails miserably. Grow your own. 

Good luck.
